How to Balance pH for White Mulberry Plants

Maintaining the proper soil pH is crucial for the healthy growth and development of white mulberry plants. This comprehensive guide will walk you through the step-by-step process of testing, amending, and monitoring the pH levels to ensure your white mulberry thrives.

Soil pH Testing for White Mulberry

The first step in balancing the pH for white mulberry plants is to test the soil. The ideal soil pH range for white mulberry is between 5.5 and 7.0. You can purchase a soil testing kit from a local garden center or online retailer to determine the current pH level of your soil.

To test the soil, follow the instructions provided with the testing kit. This typically involves collecting a soil sample, mixing it with the provided solution, and then comparing the resulting color to a pH scale. Make sure to test the soil in multiple areas around the planting site to get an accurate representation of the overall pH.

If the soil test reveals that the pH is too high (alkaline), you can lower it by adding elemental sulfur or a sulfur-containing product. The amount needed will depend on the current pH level and the desired pH level. As a general guideline, you can add 1 to 2 pounds of elemental sulfur per 100 square feet of soil to lower the pH by one unit.

Conversely, if the soil pH is too low (acidic), you can raise it by adding lime. The amount of lime required will also depend on the current pH level and the desired pH level. A common recommendation is to add 5 to 10 pounds of lime per 100 square feet of soil to raise the pH by one unit.

Applying Soil Amendments for White Mulberry

Once you have determined the appropriate amendments needed to balance the pH, it’s time to apply them to the soil. Work the amendments into the soil to a depth of 6 to 8 inches, ensuring that the entire root zone is affected. This can be done using a rototiller, garden fork, or other soil-mixing tool.

After applying the amendments, wait a few weeks before testing the soil again to allow the pH to adjust. This will give you a more accurate reading of the soil’s current pH level.

Monitoring Soil pH for White Mulberry

Maintaining the proper soil pH for white mulberry is an ongoing process. Continue to monitor the pH level annually or bi-annually to ensure it remains within the ideal range of 5.5 to 7.0. If necessary, make additional adjustments to the soil by applying more amendments as needed.

Other Factors for Growing White Mulberry

In addition to balancing the soil pH, there are other important factors to consider when growing white mulberry plants:


White mulberries prefer full sun, which means they require at least 6 hours of direct sunlight per day.


Mulberries require regular watering, especially during dry spells. However, they are relatively drought-tolerant once established.


White mulberries can tolerate a wide range of temperatures, from USDA zones 3b through 9. They are deciduous trees, meaning they drop their leaves in autumn and leaf out in spring, about two months before black and red mulberries.


When planting white mulberries, space them 35 to 50 feet apart. Dwarf varieties can be planted closer together, about 8 feet apart.

White mulberries are self-pollinating and do not require cross-pollination. However, some varieties may benefit from cross-pollination for improved fruit set and quality.

By following these guidelines and maintaining the proper soil pH, you can ensure your white mulberry plants thrive and produce an abundant harvest of delicious fruit.
